i would like to make the following suggestions for changes to this BB:
the chopping block should not be tall. it should actually be much shorter than usual, so that the blade of the cracker is about the height of your normal chopping block. that way the top of the kindling-to-be will be at the normal height and you will not have a leverage disadvantage from trying to chop wood at shoulder height.
following from that, the cracker should not be offset on your chopping block. if you still need a chopping block for using a maul, axe, or hatchet, that is best done on a block that is a different height than that of the cracker (about the height of the blade). Also, if you have many inexperienced choppers (like we do at wheaton labs), then there is a chance that someone will miss the wood (or it will kick to the side) and the maul will hit the metal of the cracker.
i understand that paul wants all objects to be made for use by giants, but chopping blocks are safer and easier to use if they are the appropriate height for the most common user.
